The extraterrestrials are just plain done with us. The Cold War has ended, and so has their fascination with our nuclear missile silos. So maybe they've just declared "mission accomplished," and gone away.

But here's another possibility.

Why the Earth Will Never Be Invaded

Cosmologists propose that the universe was until recently a lifeless collection of particles. But they have ignored a critical component of the cosmos because they don't know what to do with it. This component, consciousness, is an utter mystery. How did inert, random bits of matter ever morph into Obama or Lady Gaga?

Seth Shostak

It seems that the frequency of planets able to support life is roughly one percent. In other words, a billion or more such worlds exist in our galaxy alone. That's a lot of acreage, and it takes industrial-strength credulity to believe it's all bleakly barren.
